Washington was perceived to be among the richest and in fact was anything but. I strongly urge you read Chernow's Washington: A Life. He was not so well off as people then (and since) have thought. Indeed, the poor man was put upon by so many people (for food, lodging and entertainment, as well as loans) that it's a wonder he didn't perish in debtor's prison. He found that his slaves were, in fact, a drain on his resources rather than a profitable venture.

"No. 1 -- George Washington
George Washington was not only “first in the hearts of his countrymen,” but he was also the richest president in our nation’s history.
How do we measure Washington’s wealth? Measuring across centuries has its challenges. One approach is to estimate the value of his property when he was alive and adjust for inflation. Another is to look at his wealth as a percentage of gross domestic product. A third is to compare his income to the national budget. Each approach leads to huge numbers.
For the first 100 years of our nation, wealth was measured mostly by land and slaves. Washington inherited ten slaves from his father at age eleven. He eventually owned more than 8,000 acres of prime farmland near what is now Washington, D.C., and more than 300 slaves. His wife, Martha, was also very wealthy, both from her dowry and inheritance from her first husband, one of the wealthiest men in Virginia. She inherited one-third of his 17,000 acres of land and 300 slaves as well as $129,650 in Colonial Virginia currency estimated by historians at Washington and Lee University to be worth $6 million in 1986.
At the time of his death, Washington’s land, slaves, house, horses and personal belongings were worth about $525,000, which has been estimated to be worth $525 million today.
In 1996, a study to calculate the 100 richest people ever in the U.S. ranked Washington 59th, the only president on the list. His net worth was estimated to be 1/777, or 0.13 percent, of GDP. By that measure, John D. Rockefeller was the wealthiest American ever. His wealth equaled 1.5 percent of GDP. Bill Gates worth about $60 billion, or about 0.4 percent of GDP, would be in the top ten.
Washington’s salary as president was 2 percent of the Federal budget in 1789, which would amount to $60 billion today. To be fair, the budget was different 225 years ago, when there was no income tax and most federal government spending was defense. Even so, 2 percent of today’s defense budget would be $2 billion per year.
For his time, Washington was incredibly wealthy, but he didn’t have air conditioning or toilets. He got strep throat riding his horse in the snow and died two days later. Today, a common antibiotic would have had him back on his horse within days."
Poor dude. My heart bleeds for his sufferings
